Answer: tanA=3/4
Step-by-step explanation: If cosA=4/5 then
sinA=√(1−cos2A) {Because sin^2A+cos^2A=1}
=>sinA=√(1−16/25)
=>sinA=√(9/25)
=>sinA=3/5
Now as tanA=sinA/cosA
=>tanA=3/5×5/4 {Because 1/cosA=5/4}
=>tanA=3/4

Recursive Formula--
It is the formula which is used to represent the nth term of a sequence in terms of (n-1)th term of the sequence.
Here we are given a table of values by:
n f(n)
1 4
2 20
3 100
i.e. when n=1 we have:
